Peers not syncing

$

I am using a very simple peer setup in my config file, but the stick-table data does not seem to be syncing. Upon initial startup of peer1, I see (via tcpdump) a bit of traffic to peer2, but then nothing ever gets sent again, even as I change the table data (via stats socket). Is there anything additional I can do to debug this?

For what it’s worth, this is the tcpdump output

bash-5.0# tcpdump -i any -v -nn port 1024
